Béla Harkányi (1869–1932) was a Hungarian astrophysicist, mathematician and chief observer at the Astrophysical Observatory in Ogyalla. He was the first to determine the surface temperature of stars using Planck's formula, and developed a method for determining the diameters of stars. He also wrote many popular papers.Naming citation (WGSBN Bull. 3, #3, 14), IAU / Minor Planet Center, via NASA/JPL
